- 3. THE CELL ISTHE BASIC UNIT IN ALL LIVING THINGS. CELLS ARE MICROSCOPIC. YOUR BODY HAS MANY DIFFERENT KINDS OF CELLS, EACH WITH A SPECIAL FUNCTION. GROUPS OF CELLS WITH SIMILAR FUNCTIONS COMBINE TO FORM TISSUES.
- 4. TISSUE A TISSUE ISA GROUP OF SIMILAR CELLS THAT WORK TOGETHER TO PERFORM A PARTICULAR FUNCTION.
- 6. ORGAN AN ORGAN ISA GROUP OF SIMILAR TISSUES THAT WORK TOGETHER TO PERFORM A PARTICULAR FUNCTION.
- 7. SYSTEM A GROUP OFORGANS THAT WORK TOGETHER TO PERFORM ONE OR MORE FUNCTIONS IS CALLED A SYSTEM. EACH SYSTEM PERFORMS CERTAIN FUNCTIONS, BUT NO SYSTEM WORKS TOTALLY INDEPENDENTLY. A CHANGE IN ANY ONE SYSTEM WILL AFFECT THE OTHERS.
- 8. INTEGUMENTARY MUSCULOSKELETAL RESPIRATORY CIRCULATORY DIGESTIVE URINARY NERVOUS ENDOCRINE REPRODUCTIVE LYMPHATIC IMMUNE
- 9. LARGEST SYSTEMIN THE BODY COMPOSED OF THE SKIN, NAILS, HAIR, SWEAT GLANDS, AND OIL GLANDS THE SKIN HAS TWO LAYERS THE DERMIS AND THE EPIDERMIS
- 10. IT IS THEBODY’S PROTECTIVE COVERING PROTECTION OF INTERNAL TISSUES AND ORGANS PROTECTION AGAINST INFECTION PREVENTS LOSS OF WATER ELIMINATION OF WASTE STORAGE OF NUTRIENTS DETECTION OF TOUCH, PRESSURE, PAIN, AND TEMPERATURE
- 11. SKIN BECOMESTHINNER AND MORE FRAGILE SKIN LOSES ITS ELASTICITY CAUSING WRINKLES AND SAGGING OIL GLANDS ARE LESS ACTIVE CAUSING DRY SKIN LOSS OF FAT LAYER LEAVES THE SKIN WITH LESS PROTECTION AND LESS INSULATION DECREASED SENSITIVITY OF NERVE ENDINGS HAIR COLOR FADES NAILS BECOME THICK AND TOUGH DEVELOPMENT OF SKIN IRREGULARITIES SUCH AS SKIN TAGS, MOLES, AND WARTS DEVELOP BROWN SPOTS ON WRISTS AND HANDS
- 12. PREVENT SKINBREAKDOWN PROTECT FROM INJURIES DUE TO LOSS OF SENSATION KEEP WARM AND AWAY FROM DRAFTS APPLY LOTIONS OR CREAMS TO PREVENT DRY SKIN BATHE ONLY ONCE OR TWICE A WEEK TO PREVENT DRY SKIN HAVE RN SCHEDULE PODIATRIST FOR NAIL CARE APPLY SOCKS TO KEEP THE FEET WARM ASSIST WITH NUTRITION
- 13. COMPOSED OFBONES AND JOINTS JOINTS ARE PLACES WHERE BONES COME TOGETHER AND THERE IS THE POSSIBILITY OF MOVEMENT BONES ARE CONNECTED TO EACH OTHER BY LIGAMENTS 206 BONES IN OUR BODY
- 14. MUSCLES 3 TYPESOF MUSCLE TISSUE SKELETAL SMOOTH CARDIAC MUSCLES MAY BE VOLUNTARY OR INVOLUNTARY TENDONS CONNECT MUSCLE TO BONE LIGAMENTS CONNECT BONE TO BONE
- 15. PROVIDES STRUCTURALSUPPORT AND FRAMEWORK FOR THE BODY PRODUCE MOVEMENT PROTECT TISSUES AND ORGANS PRODUCE BLOOD CELLS IN BONE MARROW MAINTAIN POSTURE AND BODY POSITION MAINTAIN BODY TEMPERATURE
- 16. STRENGTH ANDENDURANCE DECREASE BODY MOVEMENTS SLOW MUSCLES WEAKEN, BECOME SMALLER, AND LOSE ELASTICITY MUSCLE WEAKNESS CAN AFFECT ANY SYSTEM OF THE BODY JOINTS BECOME STIFF BONES BECOME THIN AND BRITTLE AND CAN BE EASILY BROKEN CHANGES IN THE SPINAL COLUMN RESULT IN STOOPED POSTURE
- 17. PROTECT AGAINSTFALLS MOVE PERSON GENTLY ASSIST WITH AMBULATION ASSIST WITH RANGE-OF-MOTION EXERCISES ASSIST WITH NUTRITION
- 18. COMPOSED OF THEBRAIN, SPINAL CORD, AND NERVES. DIVIDED INTO TWO PARTS – THE CENTRAL NERVOUS SYSTEM AND THE PERIPHERAL NERVOUS SYSTEM.
- 19. CONTROLS ANDCOORDINATES BODY ACTIVITIES PROVIDES SENSATIONS FROM THE ENVIRONMENT THE BODY’S COMMUNICATION CENTER CONTROLS THE PRODUCTION OF HORMONES
- 20. MADE UP THEBRAIN AND SPINAL CORD COORDINATES MOST BODY ACTIVITIES EACH PART OF THE BRAIN CONTROLS SPECIFIC FUNCTIONS THE RIGHT SIDE OF THE BRAIN CONTROLS THE LEFT SIDE OF THE BODY AND VICE VERSA THE BRAIN IS PROTECTED BY THE SKULL
- 21. NERVES ENTERINGAND LEAVING THE SPINAL CORD CARRY IMPULSES TO AND FROM THE BRAIN THE BRAIN AND SPINAL CORD MAKE UP THE CENTRAL NERVOUS SYSTEM
- 22. NERVES NERVES CARRYIMPULSES TO AND FROM THE BRAIN 12 PAIRS OF CRANIAL NERVES CONDUCT IMPULSES BETWEEN THE BRAIN AND THE HEAD, NECK, CHEST, AND ABDOMEN 31 PAIRS OF SPINAL NERVES CONDUCT THE IMPULSES FROM THE SKIN, ARMS, LEGS, AND INTERNAL STRUCTURES
- 23. THE NUMBEROF NEURONS ( BRAIN CELLS ) DECREASE THERE IS REDUCED BLOOD FLOW TO THE BRAIN TRANSMISSION OF MESSAGES IS DELAYED, RESULTING IN SLOWER RESPONSES AND REFLEXES SHORT TERM MEMORY LOSS MAY OCCUR DECREASE IN SENSITIVITY OF NERVE ENDINGS IN THE SKIN
- 24. PROTECT FROMFALLS AND INJURIES PROVIDE REST PERIODS
- 25. EYE SENSE ORGANFOR VISION THE WHITE PART OF THE EYE IS CALLED THE SCLERA THE COLORED PART OF THE EYE IS THE IRIS THE ROUND DARK OPENING THAT CHANGES SIZE IS THE PUPIL
- 26.
- 27. EAR THE EARIS RESPONSIBLE FOR HEARING AND BALANCE THE EYE TAKES LONGER TO ADJUST TO LIGHT NIGHT VISION DECREASES HEARING RECEPTORS ARE LESS SENSITIVE SENSE OF SMELL DECREASES DECREASE IN THE NUMBER OF TASTE BUDS SENSING HEAT AND COLD IS DIMINISHED
- 28. PROTECT FROMINJURY FOLLOW SAFETY MEASURES FOR HEAT AND COLD PREVENT PRESSURE ULCERS
- 29. STRUCTURES INCLUDE THE BLOOD, HEART,AND BLOOD VESSELS.
- 30. CARRY FOOD,WATER, OXYGEN, AND OTHER SUBSTANCES TO THE CELLS. COLLECT WASTE PRODUCTS AND CARRY THEM AWAY FROM THE CELLS. HELP REGULATE BODY TEMPERATURE. PROTECT THE BODY AGAINST DISEASE. MAINTAIN FLUID BALANCE.
- 31. BLOOD THE FLUIDTHAT CARRIES OXYGEN, FOOD, WASTE PRODUCTS AND OTHER SUBSTANCES THROUGHOUT THE BODY. RED BLOOD CELLS CARRY OXYGEN TO THE CELLS AND GIVE BLOOD ITS RED COLOR. WHITE BLOOD CELLS HELP PROTECT THE BODY FROM INFECTION AND ARE A PART OF THE BODY’S IMMUNE SYSTEM. PLATELETS HELP THE BLOOD TO CLOT. PLASMA IS THE LIQUID PART OF THE BLOOD.
- 32. HEART THE HEARTIS A MUSCLE THE HEART IS DIVIDED INTO FOUR CHAMBERS THE TWO UPPER CHAMBERS, THE ATRIA, RECEIVE BLOOD COMING INTO THE HEART. THE TWO LOWER CHAMBERS, THE VENTRICLES, PUMP BLOOD OUT OF THE HEART TO OTHER PARTS OF THE BODY.
- 33. BLOOD VESSELS ARTERIESCARRY BLOOD AWAY FROM THE HEART. ARTERIAL BLOOD IS RICH IN OXYGEN VEINS RETURN BLOOD TO THE HEART. VENOUS BLOOD CARRIES LITTLE OXYGEN AND A LOT OF CARBON DIOXIDE CAPILLARIES ARE TINY VESSELS THAT CONNECT THE ARTERIES AND VEINS.
- 34. THE HEARTMUSCLE WEAKENS, CAUSING THE HEART TO PUMP WITH LESS FORCE. BLOOD VESSELS LOSE THEIR ABILITY TO STRETCH AND BECOME HARD AND NARROW. FATTY DEPOSITS CLOG THE NARROWED VESSELS. BLOOD PRESSURE RISES. THE SLOWING OF CIRCULATION CAUSES PROBLEMS IN OTHER SYSTEMS OF THE BODY.
- 35. ALLOW FORREST PERIODS PROTECT FROM INJURY MAINTAIN ACTIVITY LIMITS
- 36. RESPIRATION ISTHE PROCESS OF SUPPLYING THE CELLS WITH OXYGEN AND REMOVING CARBON DIOXIDE STRUCTURES INCLUDE THE NOSE, PHARNYX, LARYNX, TRACHEA, BRONCHI, LUNGS, AND ALVEOLI THE EPIGLOTTIS PROTECTS THE OPENING TO THE TRACHEA
- 37. BRING OXYGENINTO THE BODY REMOVE CARBON DIOXIDE FROM THE BODY ALLOWS COMMUNICATION THROUGH SPEAKING AND MAKING OTHER SOUNDS
- 38. THE TRACHEA DIVIDESINTO THE LEFT AND RIGHT BRONCHI. EACH LUNG HAS ITS OWN BRONCHI BRONCHI BECOME SMALLER CALLED BRONCHIOLES BRONCHIOLES LEAD TO SMALL AIR SACS CALLED ALVEOLI BLOOD VESSELS IN THE ALVEOLI EXCHANGE OXYGEN FOR CARBON DIOXIDE
- 39. THE RESPIRATORYSYSTEM IS AFFECTED BY THE SLOWING OF BLOOD CIRCULATION AND THE WEAKENING OF MUSCLES. THE LUNG TISSUE LOSES IT’S ELASTICITY. THE RIB CAGE BECOMES MORE RIGID. THIS CAUSES LESS EXPANSION OF THE LUNGS. THE RESULT OF THESE CHANGES IN THE BODY IS A DECREASE IN THE EXCHANGE OF OXYGEN AND CARBON DIOXIDE. THIS DECREASE CAN AFFECT ALL THE OTHER BODY SYSTEMS.
- 40. POSITION FOREASIER BREATHING ASSIST WITH SECRETIONS ASSIST WITH DEEP BREATHING ENCOURAGE ACTIVITY BUT ALLOW FOR REST PERIODS
- 41. BREAKS DOWNFOOD PHYSICALLY AND CHEMICALLY SO IT CAN BE ABSORBED FOR USE BY THE CELLS. THE PRIMARY STRUCTURES ARE THE MOUTH, PHARYNX (THROAT) ESOPHAGUS, STOMACH, SMALL INTESTINE, LARGE INTESTINE AND THE LIVER.
- 42. PREPARE FOODFOR THE BODY’S USE. ELIMINATE WASTE PRODUCTS.
- 43. MOUTH SALIVARY GLANDSSECRETE DIGESTIVE JUICES THAT BEGIN THE BREAKDOWN OF THE FOOD. TEETH MECHANICALLY BREAK UP THE FOOD INTO SMALLER PIECES. PHARYNX MUSCULAR ACTION OF THE TONGUE MOVES FOOD TO THE BACK OF THE PHARYNX WHERE THE SWALLOWING REFLEX IS LOCATED.
- 44. ESOPHAGUS TUBE THATIS 10 TO 12 INCHES LONG THAT CARRIES THE FOOD TO THE STOMACH. STRONG MUSCULAR WAVES OF CONTRACTIONS CALLED PERISTALSIS MOVE THE FOOD ALONG THE TRACT. PERISTALSIS CONTINUES THROUGH THE ENTIRE DIGESTIVE TRACT.
- 45. STOMACH HOLLOW, MUSCULAR, J - SHAPED ORGAN. SECRETES DIGESTIVE JUICES TO BREAKDOWN THE FOOD. MIXES AND CHURNS THE FOOD. HOLDS THE FOOD BETWEEN 3 – 4 HOURS.
- 46. SMALL INTESTINE ABOUT20 FEET LONG BILE AND OTHER DIGESTIVE JUICES FROM THE GALLBLADDER, LIVER, AND PANCREAS ARE ADDED. FOOD DIGESTION IS COMPLETED IN THE SMALL INTESTINE. FOOD AND NUTRIENTS ARE ABSORBED INTO THE BLOODSTREAM THROUGH THE WALLS OF THE SMALL INTESTINE.
- 47. LARGE INTESTINE WATERIS REMOVED FROM THE REMAINING WASTES AND ABSORBED INTO THE BLOODSTREAM. THIS CHANGES THE WASTES INTO A MORE SOLID FORM. THE MATERIAL THAT REMAINS FORMS A SEMISOLID WASTE PRODUCT CALLED FECES. FECES ARE STORED IN THE RECTUM UNTIL THEY LEAVE THE BODY THROUGH THE ANUS.
- 48. LIVER GALLBLADDER PANCREAS THE LIVERPRODUCES BILE WHICH IS USED IN THE DIGESTION OF FATS. THE BILE IS STORED IN THE GALLBLADDER. THE PANCREAS SECRETES SOME DIGESTIVE ENZYMES.
- 49. MUSCLE TONEDECREASES THROUGHOUT THE SYSTEM CAUSING A SLOWING OF PERISTALSIS. A DECREASE IN SALIVA AND IN THE NUMBER OF TASTE BUDS CAUSES A DECREASE IN APPETITE. CHEWING AND SWALLOWING PROBLEMS MAY DEVELOP. A DECREASE IN DIGESTIVE JUICES MAKES FOOD HARDER TO DIGEST.
- 50. CHECK FORSWALLOWING DIFFICULTIES ADJUST DIET AS NEEDED MONITOR FOR CONSTIPATION
- 51. PRIMARY STRUCTURES ARE THE KIDNEYS, URETERS,BLADDER, URETHRA, AND URINARY MEATUS
- 52. REMOVES WASTESFROM THE BLOOD STREAM. ELIMINATES WASTE PRODUCTS THROUGH URINE. HELPS MAINTAIN THE BODY’S WATER AND CHEMICAL BALANCE.
- 53. KIDNEYS TWO BEANSHAPED ORGANS THE CELLS OF THE KIDNEYS (NEPHRONS) FILTER THE BLOOD AS IT PASSES THROUGH, REMOVING WASTE PRODUCTS FROM THE BLOOD. THE WASTES AND THE LIQUID THEY ARE DILUTED IN IS CALLED URINE.
- 54. URETERS TUBES THATCARRY THE URINE FROM THE KIDNEY TO THE BLADDER. THERE ARE TWO URETERS – ONE FROM EACH KIDNEY. BLADDER A MUSCULAR EXPANDABLE SAC. HOLDS THE URINE UNTIL IT IS EXPELLED. THE URGE TO URINATE USUALLY OCCURS WHEN THE BLADDER IS ONE THIRD FULL ( 200-300 ML.).
- 55. URETHRA A TUBETHAT LEADS FROM THE BLADDER TO THE OUTSIDE OF THE BODY. FEMALE URETHRA IS 1-1/2 INCHES LONG. MALE URETHRA IS ABOUT 8 INCHES LONG. URINARY MEATUS THE OPENING TO THE OUTSIDE OF THE BODY . CONTROLLED BY A SPINCTER MUSCLE
- 56. THE KIDNEYSDO NOT FILTER AS EFFICIENTLY IN THE ELDERLY PERSON ( FEWER NEPHRONS AND SLOWER CIRCULATION). WASTE PRODUCTS BUILD UP IN THE BLOOD. DECREASE IN THE MUSCLE TONE OF THE BLADDER (THE BLADDER HOLDS LESS URINE AND MAY NOT EMPTY COMPLETELY). THE SPINCTER MUSCLE WEAKENS AND MAY ALLOW URINE TO ESCAPE INVOLUNTARILY.
- 57. OBSERVE URINEOUTPUT ASSIST WITH INCONTINENCE CARE MAINTAIN ADEQUATE FLUID INTAKE
- 58. SECRETES CHEMICALS CALLEDHORMONES SECRETED INTO THE BLOODSTREAM HORMONES CONTROL AND REGULATE BODY ORGANS AND GLANDS
- 59. PITUITARY GLAND CALLEDTHE “MASTER GLAND” BECAUSE IT REGULATES THE FUNCTION OF THE OTHER GLANDS LOCATED AT THE BASE OF THE BRAIN THYROID GLAND LOCATED IN THE NECK HORMONES SECRETED AFFECT BODY GROWTH AND DEVELOPMENT REGULATES METABOLISM PANCREAS LOCATED NEAR THE SMALL INTESTINE PRODUCES INSULIN
- 60. PROTECTS THEBODY FROM DISEASE AND INFECTION DEFENDS AGAINST THREATS FROM INSIDE AND OUTSIDE OF THE BODY WHEN THE BODY SENSES AN UNWANTED SUBSTANCE THE IMMUNE SYSTEM ACTS
